Cube is a high-performance, scalable and modular layer-1 public chain capable of supporting multichain and cross-chain architecture. Compatible with EVM and Cosmos ecosystems, Cube is committed to developing decentralized cross-chain protocols and Web3 infrastructure for the next-generation multichain experience.How it worksThe key architecture behind Cube splits the blockchain’s functions to optimize performance, security and scalability. Cube is designed with an execution layer for transactions by using the ZK rollup-based Validium solution and a self-developed collaborative-rollup solution as the system’s execution engine. Consensus-wise, Cube uses a settlement layer that’s fully compatible with Ethereum Virtual Machine (EVM) and Ethereum protocols, introducing a high-performance consensus protocol that supports large-scale node participation. Regarding raw data storage for transactions, Cube Chain has a data-availability layer that implements block data-sharding and -sampling validation schemes to provide efficient, reliable storage services.
